Klarna Software Engineer interview questions

Recruiter found me by email. First round question was on my experience Second round was online code test Third round was skill test on screen. Forth round is behavioral interview on screen. I think that, Skill test interviewer has some bias. There are some answers in his mind. In fact there are many alternatives in engineering. There is not only one right answer. Even if there was arranged behavioral interview after in minutes. I was called and cancelled the interview due to his feedback unexpectedly. This is unprofessional and embarrassing.

I was contacted by a recruiter. First I recieved an online coding test. Then I had a remote technical and HR interview. Final stage was an onsite interview. There were three rounds which are system design interview, a logic test and an HR interview.
